Overview

This project involved the development of a connected outdoor lighting system for a private customer, combining custom hardware, embedded software, and mobile application development into a single solution. The objective was to create a reliable garden light that could operate independently while also offering convenient wireless configuration and control.

The system was built around an ESP32 microcontroller and featured custom-designed electronics, firmware, and a dedicated mobile application. In addition to wireless connectivity, the project included PCB development, enclosure design, and preparation for small-scale production. The resulting solution enabled flexible lighting control, configurable scenes, and a user-friendly experience tailored to residential outdoor environments.
